In 2019,ACS Infectious Diseases included an article by Rey-Varela, Diego; Cisneros-Sureda, Javier; Balado, Miguel; Rodriguez, Jaime; Lemos, Manuel L.; Jimenez, Carlos. Computed Properties of C10H22N2O2. The article was titled 《The Outer Membrane Protein FstC of Aeromonas salmonicida subsp. salmonicida Acts as Receptor for Amonabactin Siderophores and Displays a Wide Ligand Plasticity. Structure-Activity Relationships of Synthetic Amonabactin Analogues》. The information in the text is summarized as follows:
Amonabactins are a group of four related catecholate siderophores produced by several species of the genus Aeromonas, including A. hydrophila and the fish pathogen A. salmonicida subsp. salmonicida. Although the gene cluster encoding amonabactin biosynthesis also contains a gene that could encode the ferri-siderophore receptor (fstC), to date there is no exptl. evidence to explain its role. In this work, we report the identification of the amonabactins’ outer membrane receptor and the determination of the minimal structural parts of these siderophores involved in the mol. recognition by their cognate receptor. The four natural amonabactin forms (P750, T789, P693, and T732) and some mono and biscatecholate amonabactin analogs were chem. synthesized, and their siderophore activity on A. salmonicida FstC(+) and FstC(-) strains was evaluated. The results showed that each amonabactin form has quite different growth promotion activity, with P750 and T789 the most active. The outer membrane receptor FstC recognizes more efficiently biscatecholate siderophores in which the length of the linker between the two iron-binding catecholamide units is 15 atoms (P750 and T789) instead of 12 atoms (P693 and T732). Anal. of the siderophore activity of synthetic analogs indicated that the presence of Phe or Trp residues is not required for siderophore recognition. The results together point toward evidence that the amonabactin receptor FstC admits a high degree of ligand plasticity. We also showed that FstC is present in most Aeromonas species, including relevant human and animal pathogens as A. hydrophila. From the results obtained, we concluded that the ferri-amonabactin uptake pathway involving the outer membrane transporter FstC possesses a considerable functional plasticity that could be exploited for delivery of antimicrobial compounds into the cell. This would allow the use of the siderophore-based iron uptake mechanisms to combat infections caused by species of the genus Aeromonas. The results came from multiple reactions, including the reaction of tert-Butyl (5-aminopentyl)carbamate(cas: 51644-96-3Computed Properties of C10H22N2O2)
Some of the reported applications of tert-Butyl (5-aminopentyl)carbamate(cas: 51644-96-3) include: synthesis of of a supermacrocycle that self-assemble to form organic nanotubes., preparation of water-soluble unsymmetrical sulforhodamine fluorophores from monobrominated sulfoxanthene dye, synthesis of functionalized porphyrins as biocompatible carrier system for photodynamic therapy (PDT).Computed Properties of C10H22N2O2
